style="font-size:16px;">1、避雷針，又名防雷針、接閃桿，是用來(lái)保護(hù)建筑物、高大樹(shù)木等避免雷擊的裝置。在被保護(hù)物頂端安裝一根接閃器，用符合規(guī)格導(dǎo)線與埋在地下的泄流地網(wǎng)連接起來(lái)。避雷針規(guī)格必須符合GB標(biāo)準(zhǔn)，每一個(gè)防雷類別需要的避雷針高度規(guī)格都不一樣。 2、當(dāng)雷云放電接近地面時(shí)它使地面電場(chǎng)發(fā)生畸變。在避雷針的頂端，形成局部電場(chǎng)集中的空間，以影響雷電先導(dǎo)放電的發(fā)展方向，引導(dǎo)雷電向避雷針?lè)烹姡偻ㄟ^(guò)接地引下線和接地裝置將雷電流引入大地，從而使被保護(hù)物體免遭雷擊。 3、由于避雷針的構(gòu)造和作用，我們要特別注意保持避雷針的良好導(dǎo)電性。一旦有一處聯(lián)接不好，或斷了，斷口以上的一段就成為一個(gè)隔離的導(dǎo)電系統(tǒng)。 4、當(dāng)云中有電荷時(shí)，這隔出的部分上部感應(yīng)出與云中電異號(hào)的電荷，而下部感應(yīng)出與云中電同號(hào)的電荷，如果上部和云中電起放電作用時(shí)，強(qiáng)大的放電電流只能通過(guò)建筑物放出大量熱量，于是引起雷擊。這樣不但不能避雷，反而還招來(lái)雷禍。為防意外，高大建筑物豎起幾條避雷針。另外，每一又避雷針只能保護(hù)一定的建筑面積。對(duì)于較大的建筑物也需要豎起幾條避雷針。</span>

style="font-size:16px;">據(jù)中國(guó)的規(guī)范規(guī)定，單支避雷針的保護(hù)范圍是一個(gè)錐體，高度為h的避雷針，其在地面上的保護(hù)半徑r=1.5h；在被保護(hù)物高度hx的水平面上，其保護(hù)半徑rx為：rx=(1.5h-2hx)P。 “折線法”是比較成熟的方法，在電力系統(tǒng)又稱“規(guī)程法”，即單支避雷針的保護(hù)范圍是一個(gè)以避雷針為軸的折線圓錐體。單支避雷針的保護(hù)范圍在DL/T620-997《交流電氣裝置的過(guò)電壓保護(hù)和絕緣配合》標(biāo)準(zhǔn)中有所規(guī)定；“滾球法”是國(guó)際電工會(huì)（IEC）推薦的接閃器保護(hù)范圍計(jì)算方法之一。我國(guó)建筑防雷規(guī)范GB50057-1994Z中也把“滾球法”強(qiáng)制作為計(jì)算避雷針保護(hù)范圍的方法。滾球法是以hR為半徑的一個(gè)球體沿需要防止擊雷的部位滾動(dòng)，當(dāng)球體只觸及接閃器（包括被用作接閃器的金屬物）或只觸及接閃器和地面（包括與大地接觸并能承受雷擊的金屬物），而不觸及需要保護(hù)的部位時(shí)，則該部分就得到接閃器的保護(hù)。</span> </p><h2> 避雷針可以避雷的原理： </h2> <p> <span style="font-size:16px;">雷雨天氣，高樓上空出現(xiàn)帶電云層時(shí)，避雷針和高樓頂部都被感應(yīng)上大量電荷，由于避雷針針頭是尖的，所以靜電感應(yīng)時(shí)，導(dǎo)體前列總是聚集了多的電荷。這樣，避雷針就聚集了大部分電荷。避雷針又與這些帶電云層形成了一個(gè)電容器，由于它較尖，即這個(gè)電容器的兩極板正對(duì)面積很小，電容也就很小，也就是說(shuō)它所能容納的電荷很少。而它又聚集了大部分電荷，所以，當(dāng)云層上電荷較多時(shí)，避雷針與云層之間的空氣就很容易被擊穿，成為導(dǎo)體。這樣，帶電云層與避雷針形成通路，而避雷針又是接地的，避雷針就可以把云層上的電荷導(dǎo)入大地，使其不對(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。按我國(guó)統(tǒng)計(jì)的雷電流幅值約為300 kA，其對(duì)應(yīng)的雷擊高度為408 m。取雷擊定位高度為400m，可得出不同高度避雷針的保護(hù)區(qū)和散擊區(qū)的地表半徑見(jiàn)表1。我國(guó)舊式民房一般高度在10 m以下，避雷帶和避雷網(wǎng)的高度與房高相同，安裝的短針?lè)览灼涓叨葹?～2 m，它們引起的散擊現(xiàn)象不明顯；高聳建筑物和高架避雷針引雷招致雷擊率增高和存在散擊區(qū)。</span> 避雷針價(jià)格，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="font-size:16px;">安裝避雷針必須遵守中華人民國(guó)家標(biāo)準(zhǔn)（GB50057—94）《建筑物防雷設(shè)計(jì)規(guī)范》，具體施工必須嚴(yán)格遵循國(guó)家標(biāo)準(zhǔn)（GB 50169—92）電氣裝置安裝工程接地裝置施工及驗(yàn)收規(guī)范，雷雨日不可進(jìn)行避雷針的安裝和檢測(cè)。 ① 定貨時(shí)請(qǐng)告知您所選用的避雷針（塔）桿的技術(shù)參數(shù)，以便廠方給您選配更規(guī)范的互連過(guò)渡接頭安裝附件。 ② 裝有避雷針的金屬筒內(nèi)體，當(dāng)其厚度不小于4mm時(shí)，可作避雷針的引下線。筒體底部應(yīng)有兩處與接地體對(duì)稱連接。 ③ 建筑物L(fēng)的防雷設(shè)施采用多根引下線時(shí)，宜在各引下線距地面的1.5～1.8m處設(shè)置斷接卡，斷接卡應(yīng)加絕緣保護(hù)措施。容 ④ 避雷針與引下線之間的連接應(yīng)采用焊接。 ⑤ 避雷針其接地裝置，應(yīng)采取自下而上的施工程序。首先安裝集中接地裝置，后安裝引下線，安裝避雷針。 ⑥ 安裝時(shí)請(qǐng)勿觸摸主接閃前列、主動(dòng)放電前列。 ⑦ 產(chǎn)品設(shè)計(jì)使用壽命20年。</span> 防雷避雷針廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！孝感建筑物避雷針廠家</p><p
